Hi
I have a small cluster consisting of 9 computers (8x2 CPUs, 1x4 CPUs).
I would like to be able to observe the output of the processes
separately during an mpirun.
What i currently do is to apply the mpirun to a shell script which
opens a xterm for each process,
which then starts the actual application.
This works, but is a bit complicated, e.g. finding the window you're
interested in among 19 others.
So i was wondering is there a possibility to capture the processes'
outputs separately, so
i can make an application in which i can switch between the different
processor outputs?
I could imagine that could be done by wrapper applications which
redirect the output over a TCP
socket to a server application.
But perhaps there is an easier way, or something like this alread does exist?
Thank You
Jody

For C I use a printf wrapper function that writes the output to a
logfile. I derive the name of the logfile from the mpi_id. It prefixes
the lines with a time-stamp, so you also get some basic profile
information. I can send you the source code if you like.
